Refer to DC Characteristics When V

, memory contents can be read, but not altered.
X can be V
or V
IH
for control and address pins, and V
PENLK
or V
PENH
for V
PEN
. See DC Characteristicsfor V

voltages.
In default mode, STS is V
when the WSM is executing internal block erase, program, or lock-bit configuration algorithms.
It is V
OH
when the WSM is not busy, in block erase suspend mode (with programming inactive), or reset/power-down
mode.
See Read Identifier Codes Commandsection for read identifier code data.
See Read Query Mode Commandsection for read query data.
Command writes involving block erase, program, or lock-bit configuration are reliably executed when V
= V
and
V
is within specification. Block erase, program, or lock-bit configuration with V
IH
< RP# < V
HH
produce spurious results
and should not be attempted.
Refer to Table 4 for valid D
IN
during a write operation.
DQ refers to DQ
0
–DQ
7
if BYTE# is low and DQ

–DQ

High Z will be V
OH
with an external pull-up resistor.
